egcs and libio.h

[Markus Kossmann <mk at emil dot inka dot de>]

When I tried to compile ddd-1997-10-08 with egcs-2.90.12 971008
(gcc2-970802 experimental) on a linux-2.1.57 libc-5.4.39 system, I got
the following error :

The problem seems to be , that the libio.h , which comes with egcs  is
not installed to /usr/include/g++ when doing a "make install". So a old
/usr/include/g++/libio.h without the _IO_flockfile macro still exists
and causes the failure. 
If  I copy  the libio.h from egcs to /usr/include/g++ the error
disappears.
